Author's in this AJM article analyzed 18 episodes. There were 225 investigations or interventions reported, averaging 14 (9-15) per episode, representing one examination every 3.1 (2.9-4.8) minutes. The most frequently prescribed investigations were magnetic resonance imaging (MRI; 13; 72%), blood sample (11; 61%), and biopsy (10; 56%). The most frequent interventions were surgery, anti-infectious treatments, and steroid treatments (9 each; 50%). Two patients (11%) died.
The population and the examination strategies used by Dr House were unrealistic. Because of this distortion, patients may not understand, nor accept the delay, the investigation choices, the intervention costs, risks, nor failures of a daily medical practice. Physicians should be aware of this “information bias.”.
